Warning Messages
If there is something wrong with the input signal, a message appears on the screen or the screen goes
blank although the power indicator LED is still on. The message may indicate that the monitor is out
of scan range or that you need to check the signal cable.
Environment
The location and the position of the monitor may influence the quality and other features of the monitor.
If there are any sub woofer speakers near the monitor, unplug and relocate the woofer to another room.
Remove all electronic devices such as radios, fans, clocks and telephones that are within 3 feet (one
meter) of the monitor.
Useful Tips
A monitor recreates visual signals received from the computer. Therefore, if there is a problem with
the computer or the video card, this can cause the monitor to become blank, have poor coloring, become
noisy, and video mode not supported, etc. In this case, first check the source of the problem, and then
contact the Service Center or your dealer.
Judging the monitor's working condition
If there is no image on the screen or a "Not Optimum Mode", "Recommended Mode 1680 x 1050
60 Hz" message comes up, disconnect the cable from the computer while the monitor is still powered
on.
If there is a message coming up on the screen or if the screen goes white, this means the monitor is in
working condition.
In this case, check the computer for trouble.
